SPECIFICATIONforming part of Letters Patent No. 607,861, dated July 26, 1898. Application filed December 20, 1897. Serial No. 662,698. (No model.)

To all whom it may concern: 7

Beit known that we, THEODOR KUNDTZ and JOSEPH GEDEON, of Cleveland, Ouyahoga county, Ohio, have invented certain new and useful Improvements in Tables or Cabinets for Sewing-Machines, &c.; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

Our invention relates to improvements in tables or cabinets for sewing-machines, &c., and more especially to a cabinet or table having a load-bearing tilting leaf whose righthand end is required to carry the greater portion of the load.

United States Letters Patent No. 590,417 were granted September 21, 1897, to Theodor Kundtz, one of the present applicants, for an invention involving novel and desirable mechanism for actuating the tilting leaf that bears the sewing-machine head or other machine.

The primary object of our present invention is to adapt the invention that is disclosed and claimed in the said Letters Patent particularly to a table or cabinet having a tilting leaf whose right-hand end is required to bear the greater portion of the load that is to be carried by the said leaf.

With this object in view and to the end of realizing other advantages hereinafter described our invention consists in certain features of construction and combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure I is a front side elevation of a table or cabinet embodying our invention. In this figure portions are in section and broken away to more clearly show the construction. Figull is an end elevation, partly in section. Fig. III is a transverse vertical section on line III III, Fig. I. Fig. IV is a vertical section on line IV IV, Fig. III; and Fig. V is a top plan of the rear portion of the left-hand end of the table and attached lifting leaf.

Referring to the drawings, A designates the top of the table or cabinet. Top A is provided centrally with a rectangular opening a,

that extends through the top. A verticallytilting leaf B is arranged to enter and occupy the said opening and is horizontally hinged or pivoted at its rear end at B to and longitudinally of the top A at the rear end of opening a. Member B is known as a load-bearing leaf and carries the sewin g-m achine head or other machine (not shown) of the table or cabinet. When the machine is not in use, leaf B is tilted downwardly below top A, as shown in dotted lines, Figs. I and II, and the said leaf is again tilted upwardly or elevated into opening a when the machine is required for use, as shown in solid lines. The said leaf B is operatively connected with the lifting leaf 0, that is horizontally hinged at one end, as at O, to and transverselyof the lefthand end of top A. The arrangement of parts is such that when the said leaf 0 is in ahorizontal position and forms a leftward extension of top A leaf B is in its elevated position, as shown in solid lines, and when the leaf 0 closes opening a and rests upon the top A the load-bearing leaf B is in its downwardly-tilted position, as shown in dotted lines, Figs. I and II, and the last-mentioned leaf is elevated or lowered, according as the lifting leaf 0 is tilted to the left or right;

The mechanism establishing operative connection between leaf B and leaf 0 is as follows:

The cabinet or table has a vertically-arranged back A. A vertically-tilting leverD is fulcrumed at or near its central portion, as at D, to the forward side of the said back and preferably centrally of the said back. The said lever at its left-hand end is operatively connected by means of a short link d with a rod d. One end of link cl is pivoted horizontally and transversely of the cabinet to the said-end of the lever, and the link (1 is correspondingly pivoted to the right-hand end of rod 61, that has its opposite end pivoted horizontally and transversely of the cabinet, as at CF, to the lifting leaf 0 a suitable distance from the hinged extremity of the said leaf. Top A and the lifting leaf 0 are suitably slotted or mortised, as at E, to accommodate the location and operation of the said rod and the link, that establishes operative connection, as already indicated, between the said rod and the aforesaid lever. The arrangement of parts is such that in the lifting leafs openposition, wherein the said leaf forms a leftward extension of the top A, rod cl is arranged horizontally, and the connected link 61 is arranged vertically, and the lever D extends from the left-hand upper corner of back A diagonally across the said back to the latters right-hand lower corner. The levers right-hand end is operatively connected with a lifting-lever G, that is arranged below the right-hand end and transversely of top A and has its rear and power end operatively attached to the last-mentioned end of lever D and has its forward end fulcrumed at G horizontally and longitudinally of top A to a bracket or member A depending from and rigid with the forward portion of the said top. A roller or wheel I) is supported from and below the central portion of the righthand end of the load-bearing leaf B and rests upon the lever G, and consequently the said leaf is elevated or lowered according as the said lever is tilted upwardly or downwardly. The operative connection between the rear and power end of the lifting-lever G and the right-hand end of lever D consists,preferably, of a chain g or other flexible connection that leads from the lifting-lever, to which the said connection is attached in any approved manner, upwardly to and over the sheave g, that is suitably attached to and at or near the upper right-hand corner of back A,and thence leads downwardly to the point at which it is attached to the lever D. The arrangement of parts is such that when the lifting leaf is in its open position, wherein the said leaf, as already indicated, forms an extension of top A, and the connected lever D extends from the said leaf in the direction of the righthand lower corner of back A, the aforesaid lifting-lever G is in its upwardly-tilted or elevated position, as shown in solid lines, and it is obvious, therefore, that the liftinglever is tilted downwardly or upwardly according as the lifting leaf is tilted over the opening in top A or in the opposite direction. The trend ofthe lifting-lever Gr is such, preferably, that the load carried therebyis easily raised by the person operating the lifting leaf 0 in tilting the said leaf from its closing position into its other position.

H designates an oscillating shaft that is arranged within and longitudinally of the forward end of top A forward of the left-hand end of the path of the load-bearing leaf. The said shaft at its lefthand end is provided with an operating-lever II, and the said shaft at its right-hand end is provided with an arm H that when the shaft is turned to the eX- tent and in the direction required to bring the said arm II into an upright position, as shown in Figs. III and IV, engages the under side of a plate or bar B secured to the under side of leaf B, when the latter is in its upwardly-tilted position, and thereby affords bearing for the forward portion of the said leaf in the said position. Of course the top A is suitably mortised or recessed, as at A to accommodate the location and operation of the members H and H of the shaft H.

What we claim is 1. In a table or cabinet of the character indicated, the combination with the top A having an opening therethrough, a verticallytilting load carrying leaf B horizontally hinged or pivoted to the said top and arranged to occupy the opening in the said top in its upwardly-tilted position, and a lifting leaf 0 hinged horizontally at the left-hand end of the top; of a suitably-supported vertically-tilting lever having a sweep below the rear end of the top, operative connection between the lifting leaf and the said lever, a suitably-supported lifting-lever arranged below and transversely of the right-hand end of the loadcarrying leaf and operatively connected with the first-mentioned lever, and a roller or' wheel resting upon the said lever and supported from the aforesaid load-carrying leaf, and the arrangement of parts being such that the load-carrying leaf is tilted downwardly or upwardly according as the lifting leaf is tilted over the opening in the top of the table or cabinet or in the opposite direction, substantially as and for the purpose set forth.

2. In a table or cabinet of the character indicated, the combination with the top A havin g an opening therethrough, a vertically-tilting load-carrying leaf B horizontally hinged or pivoted to the said top and arranged to occupy the opening in the said top in its upwardly-tilted position, and the lifting leaf 0 hinged horizontally and transversely of the cabinet at the left-hand end of the top; of a vertically-tilting lever fulcrumed at or near its central portion and arranged longitudinally of the cabinet and below the rear end of the top, operative connection between the lifting leaf and the left-hand end of the said lever, a suitably-supported lifting-lever arranged below and transversely of the righthand end of the load-carrying leaf, a roller or wheel resting upon the said lever and supported from the aforesaid load-carrying leaf,

and a suitably-guided chain or flexible connection between and operatively connecting together the aforesaid levers, substantially as and for the purpose set forth.
